Bird Colony Island Shoreline Protection Services

This project for Sarasota County involved stabilizing the shorelines of three mangrove islands in the Intracoastal Waterway just south of the Siesta Drive bridge. This area had experienced a considerable amount of erosion due to currents and waves from boat wakes. Atkins provided turnkey professional coastal engineering services including bathymetric surveys, geotechnical investigations, feasibility study drawings, volume calculations, construction plans, bidding support, and construction oversight. Atkins ecologists provided advice to establish marsh elevations for specific planting regimes. Dredge material was deposited to optimize planting success and further enhance erosion protection. The project also included the construction of a 1,250-linear-foot breakwater, and backfilling with dredged material to create an inland marsh to enhance and protect a vital wading bird rookery in Roberts Bay. Roberts Bay is located south of Sarasota Bay and inland of northern Siesta Key.
